PUDDLlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 577,109, dated February16, 1897. Application filed June 18, 1896. Serial No. 596,055. KNomodel.)

To all whom it may concern-- Be it known that I, LOUIS J. MORGAN, acitizen of the United States, residing at Indianapolis, in the county ofMarion and State of Indiana, have invented certain new and usefulImprovements in Puddling-Tools, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to improvements in that class of tools used forstirring the molten mass of metal in puddling-furnaces, and moreparticularly to improvements upon the puddling-tool of Patent No.550,368, granted to Henry B. Hall and dated November 26, 189-5.

The puddling-tool heretofore in use is so constructed that it becomesnecessary, after the charge in the furnace has been sufficientlypuddled, to remove it by means of tongs or other suitable devices fromthe puddlingchamber and to replace it in the puddlingchamber before theintroduction of a new charge, whereby considerable time and labor areexpended.

The object of my invention is to provide a puddling-tool whereby I amable to dispense with the removing and replacing of the tool, as aboveset forth, thereby saving time and labor.

A further object of the invention is to provide a puddling-tool thatwill be much lighter in weight than any of those heretofore used,thereby enabling me to use less motive power than formerly required inrotating the tool.

The invention consists, essentially, of a puddling-tool within whichwater is made to circulate while the tool is in operation, and also ofthe novel features of construction hereinafter set forth and described,and more particularly pointed out in the claims hereto appended.

Referring to the drawings, Figure 1 is a central longitudinal section ofthe preferred form of tool in position, with the middle chamber of thepuddling-furnace shown in section. Fig. 2 is a transverse section of thestirring bar or tool, taken on the line 2 2 of Fig. 1. Fig. 3 isalongitudinal section of a modification of the tool; and Figs. 4 and 5are respectively side views, part1 yin section, of still furthermodifications.

Like letters refer to like parts throughout the several views.

In the drawings, A denotes the walls, and B the roof of the middleportion or puddlingchamber of a puddling-furnace.

C is the hearth of the puddling-chamber, and D the bottom plate thereof.Resting upon suitable supports E F is the door or outlet of saidchamber.

The stirring bar or tool is made of iron or other suitable material andadapted to rotate on the bottom of the puddling-chamber. This tool mayvary in thickness, width, and shape. It may be provided with ribs b onthe bottom, as shown in Figs. 1 and 2, or it may have a smooth bottom,as shown in Fig. 3, or it may be made in a tubular form, as shown inFigs. 4 and 5.

All the various constructions of the tool, as illustrated in thedrawings, are so constructed and arranged that water may be circulatedwithin the tool, as hereinafter de scribed, and thus the tool be keptcool during the operation of puddling.

The stirring-bar, as shown in Figs. 1 and 2, is made of one piece ofcasting, comprising the shell or outer portion a, provided with aninteriorly-screw-threaded nipple a and a cen tral portion a having aninteriorly-screwthreaded nipple a and provided with holes or openings awhich latter permit the water to circulate, as hereinafter stated.

In the construction shown in Fig. 3 the stirring-bar is made of a singlehollow casting provided with the interiorly-threaded nipple a. In place,however, of the central portion ct of the construction last abovedescribed there is substituted a water-circulating pipe consisting ofthe parts c, screwed into a plumbers T-joint 0 In the construction ofFig. 4 the tool is built up of pieces of ordinary plumbers pipe cl d,T-joint cl, nipples 01 CF, and caps d d",

and contains within it a water-circulating pipe similar to thatdescribed in connection with Fig. 3.

In the construction shown in Fig. the tool is built up similarly to thatof Fig. 4:, that is, with the pieces of a plumbers pipe 01 d, T- jointd, and caps 02 d omitting, however, the nipples d d In thismodification, Fig.

Ioo

5, the inclosed water-circulating pipe is shown as being made of lead,rubber, or cloth hose or other flexible tubing.

c is a shaft made of hollowpipe or tube of iron or other suitablematerial, which revolves in a suitable bearing 6, located in the top ofthe roof B of the puddling-chamber. The lower end of this pipe isattached to the nipple ct, Figs. 1, 2, and 3, or to the T-joint d, Figs.t and 5, by screwing the same into said nipple or joint, as the case maybe. I do not hereby,however,intend to limit my invention to this meansof connecting the shaft 6 with the stirring-bar, as it is obvious thatany suitable means may be employed without departing from the spirit ofmy invention, as long as such means of connection permits a sufficientgrip for rotating the tool. The upper end of said shaft is closed by thecollar '9 and revolves in the bearing 6 made integral with the supportf.

g is a pipe or tube made of iron or other suitable material locatedwithin the shaft 6 and adapted to rotate with it. The lower end of thispipe is attached to the nipple a Figs. 1 and 2, or to the T-joint 0Figs. 3, 4, and 5, according to the construction of the tool to be used.The upper end of this pipe fits into a sleeve g.

his an outlet-passage from the shaft 6. i is a pan surrounding saidshaft, and'k is a waste-pipe.

Z is a cog-wheel rigidly fastened to the shaft 6, adapted to mesh withthe cog-wheel m on the shaft 91, to which power may be transmitted byany well-known means.

0 is a lever fulcrumed at 0.

The operation of the device in so far as has not already been describedis as follows: When power is applied to the shaft n, the shaft 6,together V$ ith the pipe (,is caused to rotate, thereby causing thestirring bar or tool to rotate within the puddling'chamber and stir upthe molten mass of metal. During this operation of puddling water isintroduced, preferably under pressure, into the top of the pipe g.wardly through the said pipe into the bottom of the tool, Figs. 1 and 2,thence upwardly in the direction indicated by the arrows through theoutlets hinto the pan t' and off through the waste-pipe 79. In theconstruc tions shown in Figs. 3, 4, and 5 the water flows out throughthe ends of the pipe within the shell or outer portion of the tool andpasses upwardly in the direction indicated by the arrows into the hollowshaft 6 and off through the waste-pipe 7c in the manner alreadydescribed. After the charge has been sufficiently puddled the shaft 6,together with the pipe 9 and the puddling-tool, is lifted up to allowthe puddled charge to be withdrawn and a new one to be introduced byraising the lever 0. When the lever 0 is lowered, the tool resumes itsproper position on the bottom of the chamber.

The circulation of water within the shaft The water flows down-' a andtool prevents them from becoming heated during the process of puddling,and it never becomes necessary to remove the tool from thepuddling-chamber, besides permitting the tool to be made of materialmuch lighter in weight than that of the tools heretofore in use.

What I claim as my invention, and desire to have protected by LettersPatent, is-

1. In a puddling-furnace or other like structure, the combination of anupright tubular shaft with means for rotating the same, an inner tube inthe shaft with means for supplying water thereto, a horizontal hollowstirring-bar or shell, firmly secured at its middle point to the uprightshaft with the interiors in free communication, an inner hollowhorizontal portion located within the said stirringbar or shell, havingterminal outlet-passages,

and centrally connected to said inner tube with the interiors in freecommunication, whereby when water is introduced into the inner tube itwill circulate through the inner horizontal port-ion and thence throughthe shell or stirring-bar, and outward through the upright tubularshaft, while the latter is rotated, substantially as and for the purposespecified.

2. In a puddling-furnace,or otherlike structure, in combination, anupright tubular shaft c, with means for rotating the same, havingcentrally affixed to the bottom thereof a hollow stirring-bar or shell,containing a horizontal hollow member with terminal outletpassages, aninner tube 9 located in the tubular shaft 6, and means for supplyingwater to the same, said inner tube firmly secured to the middle point ofthe said tubular portion within the said stirring-bar or shell, wherebya water circulation may be maintained through tube g and the saidtubular portion within the stirring-bar, and thence outward through thesaid stirring-bar and the tubular shaft e, while the latter is beingrotated, and the stirring-bar thus kept cool during the puddlingoperation, substantially as and for the purpose specified.

3. In a puddling-furnace or other like structure, the combination of astirring bar or plate comprising an outer portion or shell to, providedwith a central portion as a made integral with said outer portion andhaving an outlet as a ahollow rotary shaft provided with an outlet, atubewithin said shaft, connections between said shaft and said outerportion and connections between said tube and said central portionwhereby water may be circulated within said stirring bar or plate, andmeans for rotating said shaft, substantially as described.

In witness whereof I have hereto affixed my signature, this 3d day ofApril, 1896, in the presence of two witnesses.
